Measurements of the electron temperature, Te, and density, ne, during the energy quench of a major disruption showed that the onset of Te erosion in the neighborhood of the m/n = 2/1 O point at the low field side (LFS) accelerates the well-known m/n = 1/1 erosion of the core temperature. During this phase Te(r) is only partially flat in the region between the q = 2 and the q = 1 surfaces and ne(r) decreases in ...
Electron temperature, Te and density, ne profiles were measured during the energy quench of a major density limit disruption in RTP (a=0.164 m, R0=0.72 m, qa=4). The evolution of the Te profile was followed with high temporal resolution (1 us) with a 20 channels ECE radiometer. High spatial (3 mm) Te and ne profiles were measured at different times during the energy quench with a Thomson scattering. With these ...
